- APPARATUS FOR SPINNING AND WINDING TEXTILE THREADS Ren Jacques Henri Kovacs, Paris, France wplication September 17, 1945, Serial No. 616,822 In France August 2, 1944 Section 1, Public Law 690, August 8, 1946 Patent expires August 2, 1964 Nowadays the spinning of textiles such as wool,

' cotton, and similar products is obtainedon fiyers after which the thread is wound up on spools on winding frames.

My invention has for its ning'and winding operations. My improved mabulk, is of a very low cost price and moreover it considerably simplifies said operations. In said machine the roving does not rotate but it is caused to twist under. the action of the rotary motion of the machine which leads to a much more regular twist of the thread.

My improved machine includes chiefly a'franie adapted to rotate around a horizontal axis and carrying a device providing for the reciprocation of a slider through a line perpendicular tothe axis of rotation while a friction driving cylinder rotates around an axis parallel with the line along which the slider reciprocates, means being provided for controlling the reciprocation of theslider and for rotating the driving cylinder and a spool carrying shaft-being provided which is parallel with the driving cylinder and yieldingly Further interesting features of my invention will appear in the reading of the following description of a form of execution given by way of example and illustrated in accompanying draw-. ing wherein:

object a machine allowing the simultaneous execution of both spin-\ 6 Claims: (Cl. 57--' 71) moving around the cylinders i3, i3 and the rotation of the shaft 8 ison the other hand transmitted through the box I to the friction driving'cylinder i5 covered with a friction material .such as cardboard, rubber or the like and parallel with the cylinders lit-I3; the axes of said cylinders l3; l3 and I5 being perpendicular to the rotary axis of the horizontal shaft 2.

The gearing contained inside the box I may be of any type. It has been assumed in the'present case by way of example that the shaft 8 ends with a worm Hi (Fig. 2) engaging a helical -wheel ll Fig. 3 is a diagrammatic cross-section illustrat- I ing the operation of the machine.

The machine includes a stationary support v iof aluminium for instance inside which may rotate a horizontal shaft 2 which may be of soft steel and which is caused to rotate through any suitable means such as a treadle or a motor. In

thepresent case, I have shown it as controlled by an electric motor 3. This shaft 2 passes through a stepped pulley 4 rigidly secured to the support I and is rigid with a frame 5 the front end of which ends in the form of a metallic ring 6. The frame 5 carries a gear box 1 inside which a shaft 8 is rotatively carried in a bracket 9 secured tothe frame 5. The shaft 8 carries another stepped pulley H connected with the pulley 4 through a belt I2.

The gears inside the box 'I transmit the rotato the axis of which is keyed a pinion i8 providing for the rotation of the guiding cylinder l3 and meshing with a pinion l9 driving the friction operating cylinder I5 and meshing in its turn with the pinion l8 which provides for the rotation of the guiding cylinder 1 3'.

Of the two sliders i4 and I4, only the slider I4 is operative and is provided with an opening 2| for the passage of the thread while the slider I4 serves only as a balancing weight as required for the high rotational speeds ofthe machine. The two sliders I4, l4 move in reverse directions along the guiding cylinders i3, i3 and cross one another at half way of said cylinders i3, I3.

The friction operating cylinder i5 is mounted in an easily interchangeable manner whereby it may bereplaced rapidly by another cylinder of a different diameter with a view toadiusting the speed of formation of the spool. This remov-' ability may be obtained by any suitable means. For instance, in Fig. 1 in which the guiding cylinders have not been shown' in the drawing for sake of clearness, it is apparent that the frictioncylinder I5 carries at its ends projections provided with transverse pins 22, 23 adapted to engage notches cut in the sockets 24, 25. The

notched socket 24 which is controlled by the pinv ion l9 cannot move longitudinally whereas the socket 25 is slidingly mounted inside the frame 5 and carries an axial rod 26 the socket 25 being urged upwardly by a spring 21; said rod 26 ends in amilled knob 28 bearing against the casing 29 forming a counterweight balancing the gear box 1 I. Obviously it is possible to draw the knob 28 tion of the shaft 8 on one hand to two guiding out for easily releasing the friction cylinder I! which may then be replaced by another cylinder. The shaft 2 is provided with a longitudinal bore which receives a stub shaft 3i, urged by a-spring. The'stub shaft.

32 also housed inside said bore. 3| carries a fork 33 diametrically guided by any conventional means such as key and slot engagement of the stub shaft 3| inside the frame Band carrying, through the agency of notches for in- 3 stance. the spool carrying spindle 34 parallel with the friction cylinder l8 and over which it is possible to insert a tube, made of cardboard or the likeadherent material as shown at 35. Obviously the spring 32 urges the spool carrying spindie 34 together with the tube 35 and the spool under formation against the friction cylinder i8.

At the end of the shaft I controlling the worm and inside the stepped pulley ii is provided an adjustable brake constituted by two fibre washers 34, 31 arranged'to either side of one of the pulley flanges. The washer 38 bears against the collar on a sleeve ll rotating together with the shaft 4 and provided with a helical thread engaging the nut 3! acting through,the agency of a spring It on a washer 81.

Lastly in Fig. 3 is illustrated the manner of providing for the guiding of the slider, i4 over the guiding cylinder l3. This slider is provided at its rear end with two pins 4|! enclosing a rigid guiding rod 42. This arrangement obviously prevents the slider from rotating with reference to the guiding cylinder It. On the other hand, in order to provide for the guiding of the slider inside the helical groove of the cylinder N, there is arranged a guiding member 43 engaging the grooves through a certain length, a small collar 44 on said member and a tail piece 45 therefor forming a projection engaging loosely a perforation in the threaded block screwed inside a bore of the slide I4. I obtain thereby an excellent guiding for the slider inside the helical grooves of the guiding cylinder l3 chiefly at the extreme points" at which the slider ends its movement in a direction and beginning its movement in the reverse direction. As a matter of fact as the collar 44 has the possibility of moving upto the surface of the threaded block 48 and by reason of the possibility for theprojection to rock inside said block, the guiding member 43 may follow the groove while rocking slightly withreference thereto without leaving it and without 4 being wedged.

The operation of the machine is as follows: The roving 48 (Pig. 3) coming from a tensioning'guiding member 49 passes through the opening II in the slider l4 and is engaged between the frictional operative cylinder l5 and the cardboard tube which is at this moment urged into contact with the cylinder is and the end of' the roving is maintained in a slot provided in said card-board tube 35; after a few revolutions have been executed by hand the machine is started. The arrangement formed by the shaft 2, the frame I and the fork 33 is started rotating at a speed which is for instance of the order of 700 R. P. M., whereas the pulley Ii which rotates under the action of said rotary movement cates along the cylinder l3 whereby it providesfor the twisting of the thread and its winding around the spindle 44 through the frictional action between said spindle and the friction cylinderv I 5 and then between the spool 5| thus being formed and this same friction cylinder.

when the belt i2 is caused to pass from one step of the ulleys 4 and ii onto the other, this leads obviously to the obtention of two different speeds for the shaft 8, which modifies by way of consequence the twist of the thread and the speed of winding.
